Re: [Quickfix-developers] compile problems with tradeclientgui

[<OM...@th...>]

Alex,

Yes, we did get it and were able to get those examples to work properly,
thank you very much.  However we added some new scenarios to that project
that we could not get working.  John and I were actually discussing this a
couple days ago.  I'd like to send you that project and perhaps you can
give some insight on why it isn't working.  One of us will post our new
example sometime today.

Hi Oren,

I recently sent a demonstration project that shows exceptions working
with shared objects on linux. I assume you have seen this?

There is no particular problem with shared objects on linux - for a
truly massive example of their use see the ACE+TAO CORBA ORB at
http://www.cs.wustl.edu/~schmidt/TAO.html. We have been using this for
around three years - exceptions work fine.

With quickfix 1.1 I have been able to build shared libraries and link
the example C++ programs to then. They work fine.

If you need further assistance I may be able to help with another
exception demonstration program.

Even if you still have JNI problems, perhaps you could still enable
shared libs anyway - after all they are useful and working in C++
already.

Cheers,
Alex.
